To all whom z't may concern: a l

Be it known that LI-IARRY C. CLAY, aciti zenof the United States, residingat Columbus, in the county of Bartholomew and State of Indiana, have invented which the follovving'is a specification.

This invention, a division of my application, Serial N 0. 120,870, filed Sept. 18,1916, for improvements in baling presses, pertains to the manner in which a division block, Which is inserted betweent baling chamber.

It is customary toemploy ablock guide adapted to receive adivision block in a osition at one side of the feed opening of a baling chamberand movable into a position and is moved by a block inserter into the in alinement Withthe feedjopening in the i generally attached path of a block inserter to the feed head so that invthe feed stroke of the latter the inserter member Will strike the block and move it into the baling chamber.

While this guiding and inserting the division blocks I have illustrated briefly: in

the drawings one form of the principal pressfin order that alclear the operation may bewhad; 1 suitable frame 5 providing out of the baling chambenthrough the feed opening 13 in timed relation With the compressing plunger." Sincjethe operation of plunger and feed head 1 is well understood nane art I will simplyl dd that While any suitable operatingmechanism may be employed With my present improvemerits, the means slioivnlrfor oscillating the feed head consistsof QlI'CL'llitI cams 14: fixed side elevation illustrating ad vls on block havmg been Jm-prop y invention relates particularly a to the means for to tliefmain drive gears and shaped tosvving I the feed head 12 up and down about the it it pivots15 of the carryinglinks 16 at the proper intervals, through the agency of the connection designatedby character 17. The

construction and operation of the foregoing mechanism is more fully j described i in my companion application mentioned above.

The tucker employed for forming an even top tothebale by tucking or folding in the looseends of the hay after theplunger has been withdrawn is in g body 18 extending transversely across one end of the feedopening 13 as shown clearly arms 19 fornied'at its onstuds 21fsein Fig. 1' and having cured tofthe outer sides 1 of the y frame.

Arcuate guards 22 bolted to the top of the frame overliethe adjacent portionsof the tucker so as to prevent hay and foreign particles from getting the form of an arcuate j between the will be raised against the tension of the spring23 and when the plunger is withdrawn thetucker will automatically fold the loose hay into the compressing chamber;

The dividing block guide and dropper of novel construction and operation will now be described. The block designated by reference character 2% may be of any suitable construction and is "shown as being built up of a plurality of boards secured together by iron cleats so as to provide a durable structure. The block holding and guiding means,

the construction of which is best shown in Flg. t, consists of a pair of parallel channel gu1des25 rlgidly secured toa cross channel bar 26'to'the ends of which are secured supporting arms 27 pivotally mounted on the stu'ds 21 at the outer sides of the tucker arms 19.: The block guide shown in an operative or set position in Fig. 4: in which the guides25 are vertically disposed above the feed: opening 13, said guide being merely held by gravity in this position with its feet 28 resting on the top of the guard brackets 22. The block guide may be swung on its pivot from this position by grasping one of the handles or bars 29 secured to the guides 25and swinging them to an upright position as indicated in dotted lines in Fig. 1. The block may be inserted in the guide when it in this block-receiving position and-at the proper time, when a bale has been compressed, the operator will. swing the guide to upright position from which the block may be ejected from the guide by a dropper carriedby the feeder head as will be presently described. 'Means for preventing displacement of the block from the guide until the blockis ejected by the dropper, consists of a yielding stop 31 pivoted intermediate its ends at 32 to the underside of the cross bar 26 and constantly urged in one direction byfa spring 33 operating on one end of the stop to carry its opposite end into the path of a block inserted in the guide. This serves as a yielding'detent to prevent the block from dropping and is adapted to yield when suflicient downward pressure is applied. to the; block thereby permitting the same to be moved down through the guide. Itwill'be noted that .when the block guide is in block-receiving position, the lower end ofthe stop 31 will'engagethe arcuate wing block.

31 of the tucker, thereby causing the stop to positively limit the extent to which the block may be inserted into the guide. Thus it is impossible when setting a block to move it too far into the guide but when the guide is moved to operative or set position the positive stop automatically becomes a yielding detent. It will be noted that when the block guide is in receiving position the tucker may operate back and forth without disturbing the locking effect it has on the stop 31.

The block will be ejected from the guide and dropped into the compressing chamber to form a division between two bales, by the action of a dropper carried by the feeder head. Thisdropper best shown in Fig. 1, is in the form of a pendant arm 35 pivotally connected at 36 to the feeder head and urged outwardly by an expansion spring 37 interposed between the head and arm, to a posi tion limited by a bolt 38 pivotally connected to the free end of arm 35, passing loosely through an aperture in the feed head and provided with an adjustable head or stop 39 for limiting the outward movement of the arm. As shown in Fig. 2, when the feeder head descends and a block is properly supported in set position it will be engaged by the dropper 35 and forced downwardly into the compressing chamber, movement of the block toward the plunger while in the chamber being prevented by the stops 4-1 projecting into the chamber from the side walls thereof. It sometimes happens that an operator will negligently or carelessly swing the block guide toward the intended set po-- sition at the wrong time, that is, after the dropper has passed below the top of the This ordinarily would result in a jam or break of more or less serious nature, but with the provision of my improvements the dropper will simply yield and pass idly by the block. Upon the following feed stroke the block, when positioned fully into set position, will be properly engaged and moved into the baling chamber. Such improper positioning of the block guide often occurs from an accidental obstruction, such for example as an accumulation of hay on the castings 22 or above the feed opening, which prevents moving the block guide fully to set position. An improper position of the block guide is shown in Fig. 3 and under this condition when the feeder head descends I the dropper will simply strike the adjacent stop, when in the position shown in Fig. 1,

inc-lined side of the block and will yield while passing downwardly across the face of the block so as not to injure or damage either the dropper, the feeder head or the block holding and guiding means.

-When the block has been dropped into the compressing chamber the next compressing stroke of the plunger will move the block into the baling chamber and past the inwardly projecting ends of spring-pressed stops 42 which prevent the block from being forced back into the compressing chamber by the expanding action of the bale. A pair of these stops 42 project through each side Wall and, as shown in Fig. 4, are pivotally mounted and yield'ingly held in stopping position by means of expansion springs 43.

I claim:

1. In a baling press, thecombination of a division block guide comprising a frame adapted to receive a division blockand movable to carry the block from a receiving position to a set position, a spring pressed detent or stop carried by the frameand serving to yieldingly oppose passage of the block therethrough, and means for causing said detent to act as a positive stop when the block guide is in receiving position and permitting the detent to function as a yieldable stop to allow the block to be passed through the guide when the latter is in said set position.

2. In a baling press, the combination of a pivotally mounted block guide movable from a block-receiving to a block-dropping position, a spring pressed detent carried by the guide for yieldingly opposing passage of a block therethrough, and an abutment with which the detent engages when the guide is in block-receiving position causing the yielding detent to function as a positive stop for preventing passage of a block through the guide.

3. In a baling press, the combination of a block guide and a tucker co-axially mounted,

(topics of this patent may be obtained for five cents each, by addressing the and a spring pressed detent mounted on the guide for yieldingly opposing passage of a block therethrough, said detent being controlled by the tucker so as to positively prevent passage of a block through the guide when the latter is in block-receiving position and to yieldingly oppose such passage when. the guide is in inoperative or set position.

4:. In abaling press, the combination of a block guide and a tucker mounted in juxtaposition, the block guide being movable from a bloclvreceiving to a block-dropping position, and means for yieldingly opposing passage of a block through the guide when the latter is in block-dropping position and influenced by the tucker when the guide is in block-receiving position to positively prevent passage of a block through the guide.

5. In a baling press, a division block inserter comprising a feed head movable into and out of the baling chamber, a blockdropper pivotally connected at its upper end to the feed head and inclined downwardly and away from the feed head so that the lower or block-engaging end of the blockdropper is substantially spaced from the feed head, a spring constantly urging the lower end of the block dropper away from the feed head, and a rigid member pivotally connected to the lower portion of the blockdropper and loosely passing through an aperture in the feed head and having an abut ment on its end projecting through said aperture for limiting movement of the blockdropper under the influence of the spring.
